The big news coming out yesterday was 19 Entertainment‘s decision to align American Idol with Universal Music Groupfor a new distribution and marketing deal, letting their previous deal with Sony Music lapse after 9 seasons. While the move is being portrayed as “dropping a bomb” by many media outlets, the decision comes as much less of a surprise within the industry. The show itself is undergoing many transitions heading into the 10th season, not to mention that creator Simon Fuller‘s relationship with new UMG co-CEO Lucian Grainge is well known, performance of Idol finalist releases have been in decline, and uncertainty about what lies ahead for some of Sony’s top brass all pointed to a likely change – as was rumored in past weeks… eMusic has announced a new CEO in Adam Klein, who has previously held positions at MTV and EMI; a new upcoming cloud-based “locker” system has also been tipped. Klein replaces JDS Capital Management/Dimensional Associates head Danny Stein who was running the music service temporarily after the exit of eMusic’s former CEO David Pakman. JDS/Dimensional also recently finalized their acquisition of The Orchard… Elsewhere, Avenged Sevenfold sees their first No. 1 on the Billboard 200 Charts with their new release Nightmare, bumping Eminem‘s Recovery from the top spot. Another impressive chart story comes from L.A. locals Best Coast, whose new release Crazy For You debuted at #36 selling over 10K in its first week… And will Spotify move into the shadows of the new digital music era, at least in the U.S., with the public launch of Rdio this week?
